1000MW二次再热超超临界汽轮机启动方式和冲转参数的选择

Start-up Mode and Turning Parameter Selection of a 1000 MW Ultra-supercritical Double-reheat Steam Turbine

相比一次再热,1 000 MW超超临界二次再热汽轮机启动面临系统复杂、启动参数更高等难点,结合某电厂1 000 MW二次再热机组生产调试过程中几次典型汽轮机启动,介绍该类型汽轮机机组在启动方式和参数控制上的优化调整。

Compared with single-reheat steam turbine, the start-up process of 1 000 MW ultra- supercritical double-reheat steam turbine is faced with such difficulties as more complex system and higher start-up parameters, etc. Combining the typical start-up process of steam turbine in a 1 000 MW double- reheat unit during production and commissioning period, an introduction is presented to the optimization and adjustment on start-up mode and parameter control of similar steam turbines.
